[mythtv-users] input selection on record weirdness

Hi,
I do have /dev/dsp3 set as the sound input of my capture card.
I also played a bit with setting the audioratelimit to 32000, but since that
I now 'enjoy' the backend crash experience which looks like a frontend
freeze. Even after resetting the value to 0 in the database it now always
crashes as soon as I start LiveTV. Before trying this, I got picture but no
sound.
This is the backend in gdb:
